Beschreibungen/Notizen
A bifunctional tethered iridium catalyst containing a 1,2-diphenylethylenediamine framework was synthesised for the first time. The ethereal tether chain was easily constructed
via
the intramolecular oxydefluorination of a perfluorophenylsulfonyl substituent by using a modified 1,2,3,4,5-pentamethylcyclopentadienyl ligand with a hydroxyalkyl chain. The conformationally constrained structure could hamper deactivation pathways in the catalytic hydrogen generation from formic acid, leading to advanced durability and complete conversion.
A bifunctional
O
-tethered Ir complex containing a 1,2-diphenylethylenediamine framework is newly developed. The tether linkage contributes to exceptional durability in the catalytic dehydrogenation from formic acid by hampering deactivation pathways.
